TO ALL WIIOM IT MAY CONCERN:

Be it known that I, GEORGE LANE, of the city, county, and State of New York, have invented a new and useful Improvement in Door-Hinges; and I dohereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure 1 represents a side elevation, partly in section, of my invention.

Figure 2 Yis a horizontal sectional view ofthe same, the plane of section being indicated by the line a: z, iig. 1.

Figure 3 is a. similar view, the plane of section being indicated by the line yy, fig. 1.4

Similar letters of referenceindicate corresponding parts.

This invention relates to a new kind of door-hinges, by means of which the door will be allowed to swing open to both sides, and will be automatically closed.

The invention consists in the application of knuckles to the turning edges of the door, said knuckles tting into corresponding grooves arranged in the framework of the door, or the knuckles maybe on the frame and the grooves in the' door. The door can be swung open to both sides, and is closed by means of weights or springs arranged so in the casing ofthe door as to'close the door` from either side.

This invention will be of great value in public buildings, and wherever the doors are frequently opened and closed. The simplicity and strength of the devices will prevent the same from easily comingout of order,

and if they should require repair, they can be easily reached. They will work without noise, as there is but very little friction.

A represents the door. BA is the Vdoor-frame. C C are knuckles or beads, formed ou or secured toK the i ,turning edges of the door. D D are grooves formed in the frame B, for the knuckles to turn in, as is clearly shown in tig. 2. From g. 2 it will be easily understood that the door can be turned to both sides, the knuckle on one edge being `the pivot when the door is turned to one side, the other knuckle when the door isvturned to the other side. E E are chains or ropes, secured to the edges of the door, and passing over pulleys a a in the frame B. F F are the weights, secured to the ends of the ropes E E', and are arranged in the casing of the door-frame. Y

When the door is swung open, as in tig. 2, so as to turn on the pivot C, the rope E', which is attached to that edge on which the knuckle C is, will be drawn out and its weight, F, raised, as shown, while the rope E, on that edge on which the door turns, will'scarcely be varied in its position. When the door, after having been swung open, is released, the weight which was raised will draw it back, and will thereby close it. It' desired, one or more sets of weightsand ropes may be arranged on each door, two sets being represented in fig. 1. The knuckles and grooves may extend from top `to lbottom of the door and frame,'or may be short, arranged at` different heights, as in fig. 1.

Instead of having the knuckles on the door, they may be arranged on the fram'e, as shown in the lower part of tig. 1 and in iig. 3; the grooves will then be formed on lthe door. In this ease the grooves maybe continuedby means of curved hooks, b, which will Jrit-behind the knuckles when the door is swung open, and will steady its motions. lf the door is arranged in a narrow partition, or if it is as thick as the partition, it can with this arrangement be swung op'en s o as to describe an angle of one hundred and eighty degrees when opened.

G is a wire rod, which sustains'the weight of the door, andI prevents it from working on -the sill. The upper end of this wire is secured to the frame B, while its lower end is secured to the back` of the door, between the turning edges.

Springs can, if desired, be substituted for the weights F. A single weight, arranged in the centre between the knuckles, will, for light doors, be as eixicient as the two weights.

I claim as new, and desire to secure by Letters Patent- 1. The knuckles C C and grooves D D', when arranged on the door and its frame, substantially as described,

so as to allow the same to be swung open to both sides, as set forth.

2. The above, in combination, with the weight or weights F F', or their equivalents, made and operating substantially as and for the purpose herein shown and described.

GEORGE LANE.
